Abstract

A process is disclosed for briquetting and granulating under pressure fine grained inorganic substances, in particular metallurgical dusts, iron chips, wheel swarf, quick lime, plaster and inorganic fertilizers. The briquets or granules are stored for the purpose of waste products disposal or preferably are supplied to an efficient recycling process. The object of the invention is to obtain very solid briquets or granules with a reduced amount of binder and at the same time to improve the stability of the pressing process. For that purpose, very finely comminuted paper fibers are added to the materials to be briquetted and the homogeneous mixture of materials is compressed into briquets under compression pressures above 60 MPa.
